Lead into this activity with the introductory PowerPoint presentation and class demo of the Fun Look at Material Science lesson.) The temptation to interfere was greatest in the early days of the war, when the Government was confronted with the startling success of William Joyce, known as 'Lord Haw-Haw' to the millions of British listeners who tuned to Radio Hamburg. Through the first months of the war - the 'phoney war', in which no direct threat to the UK was evident - Haw Haw's humorous take on Britain and the British proved light relief from the dull diet of the Home Service.

Once students have read the instructions, direct each group to select reinforcement type and processing temperature range. Begin preparing the matrix resin.
No bombing raids were made on 11th/12th/13th November 1940, so everyone braced themselves for the following night 14th/15th. Science concepts. The student knows that relationships exist between the structure and properties of matter. The student is expected to: QOlal5GQaui90qp0Xm63jXnKGXbnDaeVuWh6SeNbh6Z52AL8wRmNrLKV9hlUYrPNK8QEmYDUciLoTkill6CPCbvtE5zdlRo1iQPS9 The radio war of 1939-45 is one of the great scientific battles in history. This is the story of that war. The science is explained clearly without going into overly technical language and gives a fascinating insight into a crucial period of 20th century history.

Britain at War During this time other British scientists had been able to break the Enigma code which the Germans used to send most secret messages.
Evaluate a solution to a complex real-world problem, based on scientific knowledge, student-generated sources of evidence, prioritized criteria, and tradeoff considerations.And so by the foresight and decision of one man, Professor R V Jones, in November 1940, the Wolverhampton area escaped the horror of a massive "Coventry-like" air raid. A single broadcaster would guide the bombers towards the target, but could not tell them when they were over it. To add this ranging feature, a second broadcaster similar to the first was set up so it crossed the guidance beam at the point where the bombs should be dropped. The aerials could be rotated to make the beams from two transmitters cross over the target. The bombers would fly into the beam of one and ride it until they started hearing the tones from the other (on a second receiver). When the steady "on course" sound was heard from the second beam, they dropped their bombs. I dedicate this book to my grandparents," Whipple writes in the postscript. "They met because humans were hubristic enough to think they could harness, and manipulate, the light we cannot see. Because they met, I exist."
analyze and evaluate scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing;Initially, Jones worked on his own but eventually more like-minded individuals joined him. The ability not only to develop radar but to intercept and disable the effectiveness of the enemy's systems became of paramount importance.
